Comparative Value of One-Story and Two-Story Hives 
At first glance it would seem that bees would winter better in a 
one-story hive than they would in a two-story hive, since there is less 
space to keep warm, and consequently, they would not use as much 
energy as they would in a two-story hive. If the winter stores are prop¬ 
erly arranged so that the bees will be in the upper hive body during 
the coldest part of the winter, the objection of extra room to be kept 
warm is largely overcome. Two of the requirements for good winter¬ 
ing, according to Phillips and Demuth, 1915, are, first, plenty of stores, 
and second, plenty of room for brood rearing. A two-story hive suits 
these conditions much better than a one-story hive would do. 
Table I shows that in the spring the two-storv hive in the open had 
16,406 bees, while the one-story hive had only 11,718, or a difference 
of 5,688 bees. In the windbreak, the two-story hive had 20,936 bees 
and the one-story hive had 14,063, or a difference of 6,873 bees. This
